Eyewitness Gerald McManus said: “I heard raised voices and looked out the window and saw two guys shouting at each other.

“Before I knew it one of the men was armed with a knife and tried to stab the other.

“He managed to get away and ran into his flat on the ground floor and brought out a kitchen knife.

“By this time the other guy had pulled out a hammer and struck him on the chest about eight times.

“He must have been in agony. It was horrible to watch.

“He was knocked to the ground but managed to get up and defend himself.

Police were called around 10am this morning.

“The last thing I saw was him striking the guy on the face with the knife.

“The one who started it already had a scar on his face so I imagine he’s going to have another.

“There was quite a lot of blood.”

“It’s not what I expected to see on a Sunday morning but to be honest I wouldn’t say I was too surprised.

“Assaults involving dangerous weapons are a common occurrence in the West of Scotland nowadays.

“I’ve been a victim of it myself.”

Two bus stops on Gallowgate were cordoned off by police officers after the incident.

It is believed one of the injured men got onto a bus before being stopped by officers.

A spokesperson for Police Scotland said: “Police officers attended Dalserf Court, Glasgow, at around 10.05am on Sunday morning after concerned neighbours called to report an incident involving two men.

“The men,aged 46 and 50, were traced locally shortly after and were taken to hospital. Their injuries are not thought to be life threatening.”
